This is a direct fit replacement for the Lower Control Arm caster/compliance bushing. Many S2000s suffer from frozen caster bolts and torn rubber compliance bushings. Honda does not allow the sale of just the compliance bushing alone. You must purchase an entire control arm for $353.00 MSRP per control arm. Now Ballade Sports offers not just a replacement but an enhancement for the compliance bushing. Changing from the old Rubber bushing to our Spherical Uni-ball bushing will eliminate suspension deflection and increase handling dramatically. Daily driving on this bushing will not decrease comfort.
